My boyfriend wants a 3 some with another guy..

Why is it okay to have a three some with two girls but not two guys?

Couldn't he say the same thing about you wanting a three some with another girl? Of course he wouldn't since he's interested, but you can acknowledge that point

Lots of people always assume that any guy who's in a heterosexual relationship and is willing to consider an MFM threesome must be in denial about being bi or gay.

That's true sometimes, but there are lots of other reasons guys will fantasise about this scenario.

Some guys are into it because they just love to see their woman getting off. Some guys are into it because it's sorta like being in a porn video with their woman as the star. Some guys are into it because there's some weird shit going on in their head where jealousy makes them crazy-horny. And there are other possible reasons too.

Being the centre of an MFM threesome is a pretty common fantasy for women, and some couples share this fantasy while having sex or get into role playing it. But going from fantasy to reality doesn't always work out so well, and the couple really need to talk this through in a calm way before they do anything in the real world. CDmale4male's post has some very good advice on this.

You questioning if his interest in this means he doesn't love you is, I suspect, a pretty common initial reaction for women when guys suggest this. The odds are that you were brought up to believe that the ideal is one guy-one woman, and any woman who loves her man will be faithful to him and vice versa. But now here he is, suggesting that another guy fuck you, so that must mean he doesn't value you or really care about you.

I wonder if you haven't quite grasped the fact that, for a lot of guys, there's sex... and then there's love. Many guys tend to compartmentalise the two things, whereas it's most common for women to see the two as inextricably linked. (And thus the classic post-affair scene where the guy protests, "But it was only sex!" while the woman is deeply emotionally wounded by what he's done.)

While your boyfriend is clearly very interested in this scenario, it's not uncommon for guys to suddenly realise once they're actually looking at the reality that they can't deal with the jealousy. And if your potential 'other guy' is extremely well-endowed, this could be an additional challenge for your boyfriend to overcome; lots of guys are far more insecure about the size of their penis than they're willing to admit - even to themselves.

If you're open to the idea - and it sounds like you are - then I suggest proceeding very cautiously. You may feel embarrassed about talking about this when you're not turned-on, but you really need to have a calm, rational discussion if you want to minimise the chances of the experiment messing up your relationship. In particular, you need to establish the ground rules of what you're both comfortable with and what's out of bounds, and you should agree that either one of you can call a halt at any point and the other will respect that. And, of course, at some point you need to get the 'other guy' involved, and he needs to agree to the same rules.

Finding that other guy might prove more difficult than you think (involving your ex would very obviously create a huge emotional minefield). While there's no shortage of guys who are very interested in fucking a woman, a lot of guys are hesitant to consider what some idiots call the "devil's threesome" because it involves being naked with another guy in a sexual situation and <gasp of horror!> that means it's possible another guy might touch their dick at some point, and if that should ever happen, they know they will immediately turn gay.

He probably gets off to his girl being a whore

Im thinking he might want a chance to see if he can get a chance have a huge dick in his hands and mouth.
But on a more serious note - many guys will do like your bf. They want to see you doing it, or want to see you getting fucked and you sucking another at same time ,,,,, tread lightly. If he has ANYTHING CLOSE to a jealous bone in his body you may NEVER hear the end of it about how you were enjoying the other guys cock more than his, or just he may come up with some really silly shit to say. He will say "gee whered you learn to do that" or "you never do that for me" or you might get accused of still seeing the other guy "every chance you get to go fuck him".
You HAVE GOT TO TRUST EACH OTHER that the other wont take a 3 sum as a sign as permission to go fuck around on each other. Or what if a 3sum with your ex and you or he starts having feelings again for each other.
I would say sit down and put it all in writing. Each of you will not get or be jealous then or in future due to the circumstances of said 3sum. No jealousy, no animosity, no hurt feelings, etc. Otherwise it will usually happen that someone
will accuse the other of some shady shit.
But otherwise - Hey you kids have fun.

Many ladies like a MMF threesome. Having both nipples sucked while holding two cocks and having two hands play with your pussy is quite a turn on.

I am retired now but if I was younger in my 20s and had the right woman that loves sex it would’ve been fun to do an MMF behind closed doors. I think the liberated woman nowadays experiment with lesbianism and encourage their boyfriends to suck cock so they can watch. My ex-wife liked fucking guys behind my back and then fucked me afterwards but we ended up getting divorced being a jealous guy. I think we could’ve worked something out and possibly even had a bisex MMF just to satisfy her lust for cock.

What I really like is a threesome with two other guys. A cock in my mouth and a cock in my arse. Lovely.

Op is actually a weird man

Since every guy I've dated has suggested both types, I'm guessing guys wanting both types of threesomes is normal

He probably loves you, he's just adventorous/ maybe a bit bi. Bring up that you want to have a threesum with a girl and not a guy and see where if you can get him back on track.

There is something wrong with him.
